Abstract

Elevated-temperature adsorptive separation involves the selective and rapid adsorption of gas molecules on weakly bonding chemical sites of an adsorbent at elevated temperatures (80–500 °C) and the reversible desorption of the gas molecules at a low cost. It is a significant step in several reactions, such as pre-combustion carbon capture, indirect/direct hydrogen production, ammonia separation, oxygen production from air, and carbon monoxide enrichment. This purification strategy avoids sensible heat loss of the feed gas, heat regeneration, accelerates adsorption kinetics, and can sometimes couple catalysts to achieve sorption-enhanced reactions. Before commercializing elevated-temperature adsorptive separation technologies, highly efficient syntheses for obtaining elevated-temperature-responsive adsorbents are required; competitive adsorption, interactions with gas impurities, and poisoning mechanisms need to be well understood; specific adsorption reactors and processes should also be designed. Therefore, this review covers the key progress made in terms of material design and synthesis, adsorption kinetic models and mechanisms, process design and optimization, as well as system integration for elevated-temperature adsorptive separation. This review will be valuable for the clean fossil-fuel utilization community, as well as energy and chemical industries.

用于分离应用的高温吸附剂

高温吸附分离涉及在高温(80-500℃)下，气体分子在吸附剂的弱键化学位点上的选择性和快速吸附，以及气体分子的低成本可逆解吸。它是几个反应的重要步骤，如燃烧前碳捕获、间接/直接制氢、氨分离、空气制氧和一氧化碳富集。这种净化策略避免了原料气的显热损失，热再生，加速吸附动力学，有时可以耦合催化剂来实现吸附增强反应。在高温吸附分离技术商业化之前，需要高效合成高温响应吸附剂;竞争性吸附、与气体杂质的相互作用和中毒机制需要充分了解;还应设计特定的吸附反应器和工艺。本文综述了高温吸附分离在材料设计与合成、吸附动力学模型与机理、工艺设计与优化、系统集成等方面的研究进展。该综述对清洁化石燃料利用界以及能源和化学工业具有一定的参考价值。
